DEVICE FOR S USPE NDING ARC-LAMPS.

SPECIFICATION forming part of Letters Patent No. 266,234, dated October17, 1882. Application filed m 24, use. (No model.)

To all whom it may concern:

Be it known that I, ADDISON G. WATER- HOUSE, acitizen of the UnitedStates, residing in New York, in the county and State of New York, haveinvented certain new and useful Improvements in Devices for SuspendingArc- Lamps, of which the following is a specification, reference beinghad to the drawings accompanying and forming a part of the same.

My present invention comprises a combined suspending and switchmechanism for electricarc lamps, the purpose of which is to provide aready and easy means of hanging a lamp in place and of directing thecurrent through or around the same, as occasion may require, withoutdanger of shocks to persons carelessly handling the lamps.

In the accompanying drawings, where my invention is illustrated indetail, Figure 1 is a view in elevation of the suspending and switchmechanism and the upper part of an electric lamp connected therewith.Fig. 2 is a plan view of the same devices, a portion of the tubularsupport of the lamp being shown in sec- 2 5 tion. Fig. 3 is a side andpart sectional view of the suspending and switch mechanisms,illustrating the principle of their operation.

Similar letters of reference indicate corresponding parts.

0 Thedeviceswhichformtheoperativeportions/ of the invention are designedto be secured to an overhead support, and for this purpose they areproperly clamped to a block or plate of insulating material, A.

55 Referring to Fig. 2, B and O are two metallic hooks fixed near theopposite ends of the plate A. Hook B is in metallic contact with astrip, E, electrically connected with a binding-post, G. A secondbinding-post, H, is

0 fixed to the plate A at some distance from the first, and both are ingood electrical connection with brass or copper springs D F, arranged asshown in Fig. 1, to complete circuit,

'undernormalconditions, between the said posts K is a bar, of wood orother insulating material, for convenience shaped as shown, and to it isconnected the tubular support of an electric lamp, a desirable means ofconnecting the lamp beingas follows: ThetubeL isclosed above bya cap, N,in which is a ring or eye. The bar K is recessed for the reception ofthis ring and a portion of the cap, and a hole is bored at right anglesto the ring wheninserted in position, through which hole and the ring 5is passed a pin, m, inserted in the end of a wooden bar, M. By thismeans the lamp is securely connected to the bar K and the bar M held atright angles to the tube L in such manner that it may be freely turnedby a wooden handle, P.

Fixed to the end of bar M, and immediately under the springs D F, is anarm, S, bent at right angles, as shown, so that when the handle P is ina vertical position the springs D F will be in contact; but when thehandle is turned to the position indicated by dotted lines in Fig. 1 thearm will raise the spring D out of contact with spring F.

A wire, W, is connected to the metallic arm S and to one ofthelamp-terminals, and a wire, Y, in electrical connection with a metalpin, k, fixed in the end of bar K, leads to the other lamp-terminal.

In using this device alamp is connected with 7 5 the bar K, asdescribed, or in any similar manner, and the bar hung on the hooks B Oby the pins 70 It. So long as the lamp and handle P remain in a verticalposition the springs D F are in contact and the lamp is short-cir- 8ocuited. If the handle P be turned as indicated above, the circuit ismade through the lamp alone. lfit is not desired to use the lamp, it maybe swung bodily up into a horizontal position and there retained in anyproper way, by which means the arm S is carried away from the spring Dand the lamp removed entirel y from circuit.

By the above-described devices absolute safety is insured in themanipulation of the lamps, 0 as the attendant, in repairing or cleaningthe same, or in replacing the carbons, can remove the lamp entirely fromthe circuit without taking it down, and thus avoid accidents which mightotherwise occur in many forms of lamp 5 where the circuit is completedthrough parts of the lamps when shunted from the carbons.

Having now described my invention as embodied in the most practicableand convenient mechanism of which I am at present aware, what I claim asnew, and desire to secure by Letters Patent, is-

' 1. The combination, with an insulating-base, suspending-hooks,binding-posts, and contactsprings connecting said posts, arrangedthereon, of an insulating supporting-bar, an electric lamp connectedtherewith, a switch for separating the contact-springs on the base, andcircuit-connections from the binding-posts of the base to the terminalsof the lamp, substantially as hereinbefore set forth.

2. The combination, with an insulating-base, suspending-hooks B O,spriug'rsD F, and means for connecting the same with an electriccircuit, of a bar, K, supported by said hooks, an electric lampconnected with the bar, a bar or spindle, M, extending from the bar K, ametallic contact-arm, S, fixed to the same, and circuit-connections fromthe terminals of the lamp to one of the springs and to the contactarm S,respectively, these parts being constructed and arranged for operationsubstantia-lly in the manner set forth.

In testimony whereof I have hereunto setmy hand this 16th day of May,1882.
